BABNEY GOLDMAN, OF NEW YORK, N. Y.

UNSINKABLE LIFE-BOAT.

Specification of Letters Patent.

Patented June 3, 1919.

Application led April 19, 1918. Serial No. 229,528.

To all Iwhom t 'may fon/:ern: Y

Be it known that I, BARNEY GOLDMAN, a citizen of the United States,residing at New York city`y in the county oii New York and State of NewYork, have invented new and useful Improvements in Unsinkable Life-Boats, of which the following` is a. spcciication.

This invention relates essentially to a life boat in which a number oizpersons can sit on a practically nnsinkable tubular member made tosurround the driving' mechanism for propelling the boat.

An object of the invention is to substautially form the tubular memberin a longitudinal elliptic contour so as to oder a minimum resistance tothe water and to shape it transverselyY with convex side portions togive it stability.

Another object of the invention is to provide the peculiar tubular shapemember with a series of transverse partitions to divide the tube into anumber of chambers each being an independent unit when punctured toprevent the others from filling.

The novel features of the invention are more fully described in thefollowing` speciication and claims and illustrated in the accompanyingdrawing in which :M

Figure l represents a plan view of a boat embodying this invention.

Fig. 2 is a vertical transverse section of the same.

In this drawing the numeral 5 designates a tube which is preferablyelliptic in longitudinal outline with corresponding ends so that thetube can be propelled either backward or forward. A number of transversepartitions 6 divide the tube into a series of compartments. Each end ofthe tube is provided with a fixture 7 for mounting;I a rudder 8connected to the usual cords 9 operated by a person in the boat.

The transverse portions of the tube are shaped to include a Hat top 10as indicated in Fig. 2 convex sides and semi-circular bottom withshallow contiguous walls to equipoise the tube in the water and preventit from capsizing. The outer sides of the tube are provided with anumber of rope rings 11 connected to eye xtures 12 to per mit a personswimming on the outside of the tube to grasp the rings. A railingconsisting' of a series of tubular oste 13 each be ingi screwed into asocket 4: and connected together with ropes or cables will preventanybody from fallinga olf the elliptic tube. A floor 15 is supported onthe inner convexed sides of the tubular member.

The fiat top of the tubular member forms a seat extending the length ot'the tube for supporting a number of persons who can sit on the top withtheir feet resting on the floor.

The means for propelling the tubular member consists of. a paddle wheel16 located centrally in the elliptic tubular member. The paddle wheel isrotatively mounted on a pair of standardsA 17 secured to the fioor. anda pinion 1S connected to a crank 19 can be operated by a personstandingr on the Hoor to actuate the paddle wheel. There are two cranksshown so that two persons can operate at once or it permits the operatorto always face the direction of travel without reversing the rotation ofthe crank.

It will be readily understood that when it is desired to store the boatthe tubular posts can be unscrewed and the paddle dismounted by removingthe standards, thus constitutingr a fiat package for stacking one tubeon the other. The paddle. wheel can be. mounted in place after thetubular member is thrown into the water from a ship, simply byfasteningr the standards in place and adjusting the wheel gears. Thetubular member can be stamped and shaped from thin metal and madepractically airtight to give it suilicient buoyancy. The elliptic shapewith almost sharp ends by oii'ering less resistance gives increasedspeed to the tubular member when driven through the water by a paddlewheel. The paddle wheel permits the boat to be used in shallow water orsurf without danger of grounding or turning over. The fiat top can beprovided with spaced arms to divide the top into a number of individualseats.

I claim 1. A life boat comprising an elliptic tubular member 'shaped toform a continuous hull, the said member having convexed sides and bottomwith shallow contiguous walls to equi oise the member in the water, saidmem er including a. fiat top to serve as a seat, and a deck supported onthe inner convexed sides of the member.

2. A life boat comprising an elliptic tubular member sha ed to form acontinuous hull, the said mem er having convexed sides and semicircularbottom with shallow conmy hand in the presence of two subscribingtiguous walls to eqdipbise ifle mnber in the Witnesses.

Water said member including u at top to y,

serve iis a seat, a deck supported on the inner BARNE GOLDMAN convexedsides of the member, and mtians for Witnesses:

propelling the boat.
